I certainly won't say that it's impossible, but I think it's unlikely. The symptoms mentioned there don't seem related. Also, the only one of those programs I'm using is Windows Defender, and I've been using it for over two years, but this problem only started within the last few months. (Of course, I suppose it's possible that something in Cygwin/gdb/gcc changed to make it more sensitive, or an update to Windows Defender made it more intrusive...) Failing a way to keep gdb from doing this, is there a way in gdb to stop a thread that's in "(running)" state? (Even though it's sitting at a breakpoint.) -- William M.
